Multiple Web Browsers Affected by Clickjacking

There are public reports of a new cross-browser exploit technique called “Clickjacking.” According to one of the reports, Clickjacking gives an attacker the ability to trick a user into clicking on something only barely or momentarily noticeable.

Therefore, if a user clicks on a web page, they may actually be clicking on content from another page.

A separate report indicates that this flaw affects most web browsers and that no fix is available, but that disabling browser scripting and plug-ins may help mitigate some of the risks.

An additional report suggests that Firefox users consider using the NoScript plug-in as an added preventative measure.

Disabling IFRAMEs by default, as outlined in the Securing Your Web Browser document, is reported to protect against the vulnerability.
